Worldcoin

Worldcoin (WLD) is a digital-identity and financial network built around World ID, a system that lets a person prove online that they are a unique, real human — without revealing who they are — using biometric enrollment and zero-knowledge proofs.

How World ID proves you are human

The design answers a problem that predates it but grows with AI: as bots and generated content become indistinguishable from people, platforms need proof of personhood. World ID issues a privacy-preserving credential that any app — a social network, a web3 protocol, or a government program — can check to confirm a unique human is present, enabling sybil-resistant airdrops, bot-free sign-ups, and fairer distribution. WLD is the network's token, granted to verified humans and used within the ecosystem.

Deep backing and the contested Orb

Worldcoin arrived with unusually deep venture support — a16z, Coinbase Ventures, Blockchain Capital, and Multicoin among its backers — and settles on Ethereum with an Optimism footprint. Its distinctive, and contested, mechanism is the Orb, hardware that scans irises to establish uniqueness at enrollment. That hardware dependency is both the moat and the flashpoint.

If proof-of-humanity becomes essential infrastructure

The bull case is that proof-of-humanity becomes essential infrastructure. If AI erodes trust in every online identity, a widely adopted, privacy-preserving human credential could sit beneath logins, payments, and public-benefit distribution at real scale, and Worldcoin holds the largest head start and the most capital behind that thesis.

Regulatory and structural risks around biometrics

The bear case is regulatory and structural. Biometric collection has drawn suspensions and investigations from data-protection authorities in several countries, and iris scanning at global scale raises consent, storage, and coercion concerns that zero-knowledge cryptography does not fully resolve. Token value accrual is indirect — WLD's worth tracks adoption of an identity network still proving demand — and much supply rests with the foundation and insiders, creating emission overhang. It suits holders betting on the personhood thesis and comfortable with heavy regulatory and unlock risk.

1. 1. Choose an exchange. Pick a reputable exchange that lists WLD — among the venues we rate highest are Binance, OKX and Kraken.
2. 2. Create & verify your account. Register, enable two-factor authentication, and complete identity verification (KYC).
3. 3. Deposit funds. Add money by bank transfer, card, or a stablecoin, depending on what the exchange supports in your region.
4. 4. Buy WLD. Search for WLD, choose a market or limit order, enter your amount, and confirm.
5. 5. Secure your coins. For long-term holdings, withdraw WLD to a self-custody wallet you control rather than leaving it on the exchange.
